Description

Technical Field

[0001] This invention relates to the field of rapid organic waste fertilizer production, specifically to an integrated rapid organic waste fertilizer production device. Background Technology

[0002] Organic waste possesses the dual characteristics of being both a waste and a resource: on the one hand, its high water content, easy decomposition, and tendency to produce foul odors and pathogens can lead to a series of environmental problems; on the other hand, it is rich in organic matter and nutrients, possessing significant potential recycling value. Therefore, fully utilizing the high organic matter content and other resource value of organic waste to ensure its sustainable recycling and utilization is of great importance.

[0003] Currently, commonly used resource recovery methods include incineration for power generation, landfill, anaerobic fermentation, and aerobic composting. Among these, aerobic composting is a green and environmentally friendly treatment technology that can transform organic waste into valuable resources, achieving resource recycling and environmentally friendly development. Its technology is simple and mature, with low operating costs, and the fermentation products can be used as organic fertilizer or soil conditioner, showing broad prospects for widespread application. However, current aerobic composting methods still face challenges such as long composting times, nitrogen conversion losses, and strong odors. Furthermore, the low level of equipment automation, high manual maintenance costs, and poor environmental impact limit its further development. Therefore, developing efficient, intelligent, and integrated devices is of great significance. Summary of the Invention

[0004] In order to solve the technical problems of long composting time, nitrogen conversion loss and strong odor in the field of aerobic composting, this invention provides an integrated organic waste rapid fertilizer production device and fertilizer production method.

[0005] An integrated rapid organic waste fertilizer production device is disclosed. This device is a single unit comprising a feeding machine, a crusher, a dewatering device, a mixing chamber, a stirring paddle, a spray head, a storage tank, a suction pump, a solid-liquid separator, a solid fermentation chamber, an auxiliary material feeding device, a biological agent feeding device, a humic substance inducer feeding device, a liquid fermentation chamber, a bacterial liquid metering and dosing device, an aeration device, and an exhaust gas purification device. The feeding machine is mounted on a track and works in conjunction with the crusher. Below the crusher is the dewatering device, whose outlet leads to the mixing chamber. The mixing chamber contains a stirring paddle, and a spray head is located at the top of the mixing chamber, connected to the storage tank. The system includes a sludge pump on one side of the mixing chamber, which connects to the inlet of the solid-liquid separator via a pipeline. The solid outlet of the solid-liquid separator is fed into the solid fermentation chamber. The top of the fermentation chamber is equipped with an auxiliary material feeding device, a biological agent feeding device, and a humic substance inducer feeding device. The liquid outlet of the solid-liquid separator is fed into the liquid fermentation chamber. A bacterial liquid metering and dosing device is pumped into the liquid fermentation chamber. The top of the liquid fermentation chamber is equipped with an exhaust gas outlet, which is connected to a tail gas purification device. The bottom of the liquid fermentation chamber is equipped with an aeration disc for an aeration device. The air inlet of the aeration device is connected to the air outlet of the solid fermentation chamber via a pipeline. An automatic control system interface is set on the outside of the device.

[0006] The method for producing fertilizer using the integrated organic waste rapid fertilizer production device is as follows:

[0007] The garbage bin containing organic waste is placed on the feeding machine, lifted to the feeding platform, and then tilted to feed the material, which falls into the crusher. The crushed material enters the dewatering device, and the solids are released into the mixing chamber for desalination, disinfection, and dehydration. In the mixing chamber, the spray nozzles spray the drug mixture from the storage tank, while the stirring paddle mixes the mixture. After mixing, a solid-liquid mixture is obtained. The solid-liquid mixture is transferred to the solid-liquid separator by the suction pump. The solid material discharged from the solid-liquid separator is added to the solid fermentation chamber. Auxiliary materials, biological agents, and humic inducing agents are added to the solid fermentation chamber through the auxiliary material feeding device, biological agent feeding device, and humic inducing agent feeding device. After mixing and fermentation with the solid material, solid organic fertilizer is obtained.

[0008] The liquid discharged from the solid-liquid separator enters the liquid fermentation chamber. The bacterial liquid metering and dosing device pumps the bacterial liquid into the liquid fermentation chamber, mixes it evenly and ferments it. During fermentation, aeration is carried out through an aeration device, and the exhaust gas is treated by the tail gas purification device before being discharged.

[0009] Furthermore, the organic waste is kitchen waste, sludge, distiller's grains, or livestock and poultry manure.

[0010] Furthermore, the drug mixture in the storage tank is a mixture of sodium persulfate and ferrous sulfate, with a mass ratio of ferrous sulfate to sodium persulfate of (0.5~1):1 and a concentration of 5~80g / L.

[0011] Furthermore, the auxiliary material in the auxiliary material feeding device is a mixture of peat moss, straw segments and sawdust, wherein the mass ratio of peat moss, straw segments and sawdust is 1:2:1, and the mass ratio of auxiliary material to solid material is (1~6):6.

[0012] Furthermore, the biological agent in the biological agent feeding device is a mixture of microbial agents and enzymes. The microbial agents are three or more of the following: Bacillus subtilis, Bacillus megaterium, photosynthetic bacteria, actinomycetes, Lactobacillus lactis, and Saccharomyces cerevisiae. The enzymes are a mixture of lipase, protease, pectinase, amylase, and laccase. The mass ratio of microbial agents to enzymes is (10~50):1. The amount of biological agent added is 0.01%~0.5% of the mass of the solid material.

[0013] Furthermore, the humic inducer in the humic inducer feeding device is manganese dioxide, and the amount of humic inducer added is 0.1~1.5% of the mass of the solid material.

[0014] Furthermore, the liquid medicine in the bacterial liquid metering and dosing device has the same composition as the biological agent in the biological agent feeding device. Specifically, it is prepared by propagation. The method is as follows: the biological agent and brown sugar are mixed at a mass ratio of (0.5~2):2, and then added to water and stirred to dissolve evenly. The mass ratio of the mixture of biological agent and brown sugar to water is 1:10. The fermentation temperature is controlled at 30~37℃ and the pH is less than 5.5. Fermentation is carried out for 4~10 days.

[0015] Furthermore, the aeration gas source for the aeration device 16 is air and the waste gas generated by the solid fermentation chamber 10. The aeration is turned on 2 to 5 times a day, and each time it is turned on for 30 minutes.

[0016] The exhaust gas purification device is a combination of ultraviolet light and activated carbon.

[0017] Furthermore, the weight of the remaining material in the solid fermentation chamber is x1 (kg), the weight after adding new material is x2 (kg), the moisture content is A2 (%,), the real-time fermentation weight is y (kg), and the moisture content of the remaining material is A (%,). The formula for calculating A is A=1-[(1-A)×x1+(x2-x1)×(1-A2)] / y. The initial value of A is set to 60%~95%, and A2 is set according to the moisture content of the newly added material. Each time material is added and unloaded, the data x1 and x2 are updated, and y becomes the new x1. When A < 30%, the material is discharged.

[0018] Beneficial effects of this invention:

[0019] This invention is an integrated frame, with a raw material feeding device, a crushing device, a pretreatment device, a dehydration device, a desalination, disinfection, and dehydration connection device, a solid fermentation chamber, a liquid fermentation tank, a tail gas absorption device, and other material feeding devices installed inside and outside the frame. The feeding device is located on the side. Raw materials are fed into the inlet of the crushing device through the feeding device. After being crushed, the material flows downward into the desalination, disinfection, and dehydration connection device. The solid discharge port of the desalination, disinfection, and dehydration connection device enters the fermentation chamber, while the liquid enters the liquid fermentation tank. Exhaust gas mixes with air, first passes through the liquid fermentation tank, and then is absorbed by the tail gas absorption device. The start and stop of each device are controlled through a display interface, and the operating parameters are displayed on the display interface.

[0020] This invention discloses an integrated organic waste rapid fertilizer production device, which has a high degree of automation, significant dehydration and desalination effects, can simultaneously produce solid and liquid bio-fertilizers, has a high nitrogen recovery rate, high resource utilization rate, good fertilizer quality, small footprint, and is suitable for multiple application scenarios.

[0021] (I) The fermentation time is shortened by the pre-oxidation process of advanced oxidation, and combined with the nitrogen-reducing effect of peat soil, the nitrogen loss is small and the odor is removed quickly.

[0022] (II) Manganese dioxide promotes the directional humification of organic matter, generating more humic acids such as fulvic acid, thereby increasing the added value of fertilizer;

[0023] (III) Simultaneous production of liquid fertilizer and solid fertilizer, achieving full digestion of organic waste and high resource utilization rate;

[0024] (IV) The weighing system has a high degree of automation, which has solved the problem of process control.

[0025] This invention is used for the rapid production of fertilizer from organic waste. Attached Figure Description

[0049] Experimental materials

[0050] Kitchen waste with a moisture content of 85%; chicken manure with a moisture content of 75%; auxiliary materials: peat moss, straw segments, and sawdust in a mass ratio of 1:2:1; biological agent: compound bacterial enzyme preparation; desalination disinfectant: a mixture of sodium persulfate and ferrous sulfate in a mass ratio of 1:1, with a concentration of 50g / L.

[0051] Experimental group 1 used kitchen waste as raw material and adopted the integrated organic waste rapid fertilizer production device and fertilizer production method described in the example, aerating 4 times / day, 30 minutes each time.

[0052] Control group 1 used kitchen waste as raw material, adopted traditional composting methods, and did not pre-treat the raw material. It was naturally ventilated and turned over twice a day.
